IMPROVEMENT IN MACHI NES FOR GLUING MOLDINGS.

Specification forming part of Letters Patent No. 147,097, dated February3, 1874 application filed September 19, 1872.

To all whom it may concern:

Be it known that I, J HARPER Bnowx, of Bufi'alo, in the county of Erieand State of New York, have invented a new and Improved Mode of GluingTongued and Grooved Molding and Lumber, of which the following is aspecification My invention relates to a process for gluing lumber andmoldings when in the stick, and having a tongue and groove; and itconsists in forcing or spreading a limited amount of glue into thegroove by a regulating device,

' and then inserting the end of the tongue into the end of the groove,so that the pieces to be glued shall be at an angle to each other in thedirection of their length. The end of the molding thus united is now putbetween two rollers or other compressing device, and gradually fedthrough. The gradual forcing of the tongue into the groove at an anglethereto pushes the glue in the groove before it, bringing it intocontact with the sides of the groove.

The advantage of this method of gluing tongued and grooved moldings andlumber over the old method is that theycan be glued much faster, and thegradual forcing of the tongue into the groove, as described, carries theglue the groove.

ahead of it, and brings it into contact with the sides of the groove,thus making a better joint, and also one which shall show no waste glueon its exterior. This method afiords amuch. better union of the twoparts when they are united.

The accompanying drawing shows a machine which can be used in unitingmoldin g or lumber under my process, A A being rollers, which can be setsuch distances apart as the different thicknesses of molding wouldrequire. B is a glue-pot arranged with any suitable pumping device forpumping the glue into C is the molding having the groove on its face,and D the bead having the tongue.

I do not claim ton gucd and grooved molding.

I claim- Gluing tongued and grooved molding by means of the glue-pot B,having a device for pumping the glue into the groove, and the rollers AA, arranged to force the tongue into the groove, in the mannerdescribed.
